An analysis of the seasonal outbreak of diarrhoea in children in Kathm
andu, Nepal, is reported, Vibrio cholera, 01 biotype El Tor Ogawa was
the major cause of this epidemic, The pattern of spread suggested a wa
terborne infection related to contaminated river water and this was co
nfirmed by a field survey. Although the mortality rate was low, younge
r children were more susceptible, Enteropathogenic E. coli seems to be
a major cause for diarrhoea after cholera amongst children in this st
udy.
